'Patented April 20, 1909.

Application filed March 14, 1908. Serial No. 421,178.

To all whom it may concern.

. Be it known that I, FRANKLIN L. GAINES, a citizen of the United Statesof America, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements inInvalid-Beds; and I do hereby declare the following to be a full,clear,and ,exactdescription of the invention, such as will enableothersskilled in the. art to which it appertains to make and use thesame.

M invention relates to improvements in inva id beds and its object is toprovide the same with various new and useful features, as hereinaftermore fully described and particularlycpointed out in the claims,reference being ha to the accompanyingdrawings, in which:

Figure 1 is a side elevation of a device embodying my invention; Fig. 2an end elevation of the same; Fig. 3 a detail of the-bolt for securingthe segments; Fig. 4 a detail of one corner ofthe rigid frame; Fig. 5 adetail in plan view of portions of the jointed upper frame; Fig. 6 adetail in vertical section of the rack and pinion for adjusting theupper frame; Fig. 7 the same in horizontal section; Fig. 8 a detail inelevation, with parts broken away, of the means for elevating the lowerframe; and, Fig. 9 the same in elevation at right angles to Fig. 8.

Like numbers refer to like parts in all of the figures.

The bedstead proper consists of end frames 1 connected by side rails 5preferably made of metal tubes and having on the respective corner postscastings 2, which are extended outward a short distance and connected bya transverse tubular rail 4 mounted outside the plane of the frame tomake room forthe other frames. 3 arevertical rods, which are also ofisetfrom the plane of the frame, inserted at the lower ends in the rail 41,bent inward at their upper ends, and inserted in the upper rail of theframe.

Near the'top of each corner post is a journal bearing 11 in which ismounted a rotative shaft 12 having its respective ends squared toreceive akey for rotating the same. On this shaft, adjacent to-itsrespective ends are winding drums 13 on. which are wound cables 14:extending downward and attached to the respective corners of a rigidframe 6 at the middle of which frame are hangers 7 to which are pivotedthe respective portions of a transversely divided frame 8,

respective corners of the rigi arise.

the respective outer ends of which frame are adapted to swing upward onthe pivots connecting them with the hangers 7 and are supported inadjusted position by toothed segmerits or racks 9. These racks areconnected to the frame 8 by sleeves 18 and extend downward through gearcasin s 10 near the frame 6 and are engaged by pinions 21 mounted onshafts 20 extending through the tubular ends of the rigid frame, andthrough the gear casing of the same.

The shafts 20 are also provided with squared ends to receive a suitablekey for rotating the same and the racks 9 are held in adjusted positionby spring actuated bolts 19 adapted to engage the teeth thereof, andeach withdrawn from the same by a cam lever 17 pivoted thereto.

The rigid frame 6 is vertically adjustable at its respective ends bywinding the cables 14 on the drums l3 and is held in adjusted positionby spring actuated bolts 15 extending vertically through the end frames1 and engaging ratchets 16 mounted on the shafts 12.

In use, a canvas support is attached to and supported on the bedsteadbeneath the rigid frame 6. The patient can thus be raised clear'of thebed upon the canvas and to variousinclined positions thereon or loweredupon the bed proper, as occasion may It will be noted that the gearcases also serve as corner irons for the tubular frame, and that theshafts 20 are inelosed by this frame, thus preventing anything fromwinding thereon.

' What I claim is:

1. In an invalid bed, the combination of a bedstead, a rigid frameconsisting of corner irons forming gear cases, tubular side and endrailsrigidly attached to the corner irons, a frame transversely dividedat the middle andhinged to the rigid frame, curved racks attached to theouter ends of the divided frameyand extending through the gear casings,pinions in thecasing and engaging the racks, shafts carrying the pinionsand journaled in the corner irons and extending through the tubular endrails of the rigid frame, and means for vertically adjusting for turningand holding the shafts, cables Wound on the drums and connected to theends of the rigid frame, a transversely divided frame mounted on therigid frame and pivotally attached thereto and having tubular ends,racks connected to the outer ends of the divided frame, ear easesforming corner irons of the rigid frame through which the racks extend,shafts journaled in the gear cases and extending through the tubularends of the rigid frame, pinions mounted on the shafts and engaging theracks, and spring actuated bolts engaging the racks to hold the same. I

3. In an invalid bed, the combination of a bedstead, a rigid framesupported thereon, shafts j ournaled in the end frames of the bedstead,Winding drums and ratchets on said shafts, bolts engaging the ratehets,cables i Wound on the drums, a rigid frame supported cases formingcorner irons for the rigid frame, curved racks attached to the dividedframe and extending through said eases, spring actuated bolts in thecases and engaging the racks, pinions in the cases and engaging theracks, and shafts journaled in the gear cases and carrying the pinions,and also extending through said tubular ends.

In testimony whereof I aliix my signature in presence of two witnesses.

FRANKLIN L. GAINES.
